Application filed April 29, 1920. serial No. 377,494.

To all whom it may concern:

Be it known that ii, Gnoren F. NUTTING, a citizen of the United States, and resident of the city and county of San Francisco, State of California, have invented a new and us ful @iling System for Engines,of which the following is a specificationo This invention relates to a lubricating or oiling system for motors and while it is shown as incorporated with an internal combustion engine it is to be understood that the invention is equally applicable to other types of motors and machines to the moving parts of which it is desirable to supply a lubricating medium continuously during the operation of the machine or motor.

Among the various systems that have been adopted for the lubrication of moving parts of machines and especially of the lubrication of an internal combustion engine, one system comprises the arrangement of a distributing member within the casing of the motor so as to convey a portion of a lubricating medium, such as oil, that is centrifugally thrown outwardly by the rotation of the elements of the motor, to the opposite end of the motor casing where it is discharged and permitted to gravitate into suitable pockets or sumps provided in the bottom of the casing. During the operation of the motor certain of its parts are adapted to swing into the pockets or sumps and contact with and splash the oil that may be contained therein. When a motor of this kind utilizing this system of lubrication is installed upon a motorvchicle it is obvious that when the latter is'standin or traveling on an inclined plane the oil wi l drain from the pockets or sumps or take such position that the coordinate moving parts will not contact with and be lubricated b the oil.

It is therefore one of the ob ects of the present invention to provide an improvementin such type of olling system as to insure the maintenance v of a lubricating medium upon the operating parts irrespective of the angle in which the motor casing may be positioned in ordinary use.

It is a further object of the present invention to improve the distributing means so that the oil that is delivered to the same will be projected in streams or sprays toward and on the given operating parts of the motor so that these parts willbe lubrii a a plurality o cated independently of the presence or absence of lubrication in the pockets or sumps above referred to.

A further object of the present invention is to provide means for diverting the centrifugally thrown moving oil so as to insure an ample supply of the same being delivered to the distributing means; and further to provide for the maintenance of pressure on the oil in the distributing means for the more efi'ective lubrication of the moving parts. Another object of the invention is to provide a device that is of simple, substantial and inexpensive nature, that can be readily attached to a portion of the motor casing so that the moving oil will be intercepted and directed toward the usual distributing means.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be made manifest in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that it is not intended to limit the invention to the embodiment shown by the said drawings and description as variations may be adopted within the scope of the invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of one form of motor with which this present invention is shown as incorporated.

Fig. 2 is a sectional and elevational view in a plane on the line 22 of Fig. 1.

Fig. 3 is a plan and sectional view showing the oil deflecting means as applied.

Fig. 4 is a perspective of the attachment.

The invention is illustrated as embodied with a motor having a casing part 2 in whichv is operative the usual pistons 3 and their valves, the pistons being connected to the usual crank shaft 4 by means of connecting rods 5. The crank shaft and the connecting rods operate across a chamber having a bottom ortion 6 that is provided with f sumps or pockets 7 in which sweep-the lower ends of the connecting rods which serve to splash a lubricating medium when the same collects in the pockets and thus serve to lubricate the operating parts so long as there is a lubricant in the sumps into the sumps 7.

that may be splashed by the swinging members.

In the type of motor illustrated the crank shaft is provided with a flywheel 10 inclosed in a housing or casing part 11 that may be charged with a suitable quantity of lubricating material as oil 0 and, during the operation of the motor, the rotating flywheel 10 dips into the oil Qand centrifugally throws the same outwardly to lubricate the associated parts in the housing 11. A portion of the oil that is thus thrown outwardly by centrifugal force and the rotation of the wheel 10 falls into the contiguous receiving mouth 12 of a distributing tube 13 which is extended forwardly through the crank chamber of the motor, the front end of the distributing tube 13 usually being open and freely discharging the oil that falls into the mouth 12, to the bottom of the crank chamber so that it gravitates rearwardly it is obvious that if the motor is supported in an inclined position with its axis inclining upwardly toward the front end of the motor the oil in the sumps 7 will tend to drain out or the top surfaces of the oil in the sumps will take such a position with respect to the moving parts, as the lower ends of the connecting rods, that the latter will be ineffective to splash the oil because of failure to contact with the same.

A feature of my present invention is to provide a distributing pipe 13 that is partially closed or has a reduced discharge outlet 14 at its forward end and to provide in the distributing pipe 13 a series of spray orifices 15 in such position that oil collecting in the distributlng pipe 13 will be discharged in sprays toward the reciprocating orswinging arts such as the connecting rod 5 and towar the cranks of the crank shaft 4. By restricting the discharge of the oil from the forward end of the p1pe 13 it will be seen that the oil will be caused to collect in the pipe and provide for the continuous discharge of sprays through the orifices 15 toward the operating parts.

To increase the efliciency and the reliability of the action of the lubricating system means are provided and so arranged with relation to the fiy-wheel 10 that the centrifugally thrown, moving liquid is intercepted and diverted positively toward the mouth or intake portion 12 of the distributing pipe 13. This positive deflection of the oil toward the mouth 12 is secured by means of a barrier that may be formed integrally on the internal surface of the casing 11 surrounding the fly-wheels 10 and parts that may be carried thereon, or such deflecting means may comprise a barrier part attachable to motors already constructed and in use.

A form of the divertingmeans is shown as comprising a barrler havmg a rearwardly distributor.

extending flange 16 perforated at 17 to receive screws by which it may be fastened in a position shown as in Fig; 3 angularly to the line of travel of the moving oil thrown toward the annular portion of the casing 11 about the fly-wheel 10. The barrier has a wall portion 18 designed to stand substantiall perpendicular to a contiguous surface of t e casing section 11 and at the lower part of the wall there is formed a forwardly extending lateral lip 19 spaced suficiently below or from the casing surface to provide for the passage of the thrown oil toward the wall 18. The oil in moving against the obliquely disposed wall 18 is thus diverted as in the direction of the arrow A, Fig. 3, toward the rearmost end of the barrier which is preferably provided with a funnel or guide 20 so disposed as to discharge the oil into the adjacent mouth 12 of the distributer 13. In the operation of the motor the oil is centrifugally thrown with such force as to form a substantially constant stream through the funnel or guide part 20 of the deflecting means and from the funnel is thrown forcibly across the gap and into the mouth of the distributing pipe 13 in which the oil is maintained at sufiicient pressure to cause its discharge in streams from the orifices 15 onto the connecting rods and sweeping cranks of the crank shaft. It will therefore be seen that even though the sweeping parts fail to contact with a lubricating medium in the sumps 7 the swinging parts will be lubricated by jets of oil from 100 the distributing pipe 13.

Ordinarily, during operation of motors using a lubricating system dependent on the oil thrown by centrifugal action of the flywheel, when the engine is running slow 105 there is excess oil led by the distributor to the sumps, with a resultant excess to the engine parts. When the engine is. running fast the oil is thrown so forcibly that but a small amount falls into the intake of tlie lil" By the present invention this is not only remedied, but the amount of oil led to the distributor is proportional'to the speed of the wheel, that throws itoff thus insuring a sufficiency of oil at high speed, without an excess at low speed.

What is claimed is:

1. An oiling attachment for internal combustion engines comprising a distributing pipe having discharge ports at points along its length to discharge onto given portions of the engine, and means for directing a stream of circulating oil into the distributing pipe.

2. An oiling system for internal combus- 25 tion engines 1n which oil is centrifugally thrown by a rotary'part, including a distributor having an intake disposed adjacent to the said rotary part, and a barrier longitudinally extending angularly in the direction of flow and to intercept the thrown oil and project it at pressure due to its momentum into the said intake.

3. An oiling system for internal combustion engines in which oil is centrifugally thrown by a rotary part, including a distributer having an intake disposed adjacent to the said rotary part, and a barrier longitudinally arranged obliquely to the line of movement of and to intercept the moving oil and project it into-the said intake.

4. A barrier of L-shaped cross section attachable to the wheelcasing of an internal combustion engine to divert oil, which is centrifugally thrown by a wheel in the casing, toward the intake of a distributing dewhich is centrifugally thrown by a wheel in the casing, toward the intake of a distributing device in the casing, and having a bottom flange forming a trough; said flange disposed edgewise to the moving spray or stream of oil.

In testimony whereof, I have hereunto set my hand.
